If it doesn't open,here is a synopsis: A patient is diagnosed with pituitary related Hyponatremia causing delirium. Dr. Karev's suggested treatment is 3% hypertonic saline solution given IV, 300 cc over 3 hours. What type of osmotic environment are the cell's patients exposed to? Dr. Karev's original treatment was correct! Briefly explain his choice of I.V. What type of IV would you prescribe if the patient had the opposite condition "hypernatremia"? Briefly explain your choice. What type of IV would you prescribe if the patient needed an IV, but did not have any type of osmotic imbalance? Briefly explain your choice.

Step 1
The patient is diagnosed with hyponatremia, which means they have low sodium levels in their blood. This creates a hypotonic environment, where the extracellular fluid has a lower osmolarity than the intracellular fluid. In this case, water moves into the cells, Show more…

b. What if the solute concentration outside in the beaker was greater than the solute concentration inside the osmometer? What would happen to water movement? Explain. 4. Suppose you put the same salt solution into two osmometers and place both osmometers in beakers of distilled water. You keep one osmometer setup at room temperature and put the other in a cold room at 10° C. Would you observe any differences between the two osmometers? Explain. 5. You are a physician and are treating a patient (Robert) with cholera (a bacterial intestinal infection). Robert has severe diarrhea and dehydration and, if untreated, will die in a matter of hours. Robert MUST receive fluids. Would you give Robert an intravenous infusion of distilled H2O, a hypotonic salt solution, an isotonic salt solution, or a hypertonic salt solution? Choose one and explain your choice. 7. Use your results from tubes #6 and #7 in Part F to explain the following statement: An iso-osmotic solution may not be isotonic. 8. Explain this statement: An iso-tonic solution is always iso-osmotic but an iso-osmotic solution is NOT always isotonic.

Patients who enter the emergency room dehydrated are usually given sterile saline solution intravenously. The solution administered is isotonic to prevent cell damage. What would happen if the solution was hypotonic? A. Hypotonic solutions have a higher osmotic pressure than that within cells so hemolysis can occur. B. Hypotonic solutions have a lower osmotic pressure than that within cells so hemolysis can occur. C. Hypotonic solutions have the same osmotic pressure as that within cells so hemolysis can occur.
Adi S.
A patient is to be injected with 0.4 L of an electrolyte solution in 1/2 an hour. Assuming that the solution is elevated by m above the arm and that the hydrostatic pressure alone is used to push the solution into the arm (as is typical of an IV), and assuming that the needle itself is 2.5 cm long, what inner diameter must the needle have to allow this? (Use Ě‘ = 1000 kg/mÂł and p = 1000 kg/mÂł; the values for water. Also assume that the pressure in the patient's vein is atmospheric pressure. (Calculators permitted in this question) Diameter mm Once you get an answer, try to visualize this needle to see if the dimensions make sense.
